SMCCC: Introduce function to check SMCCC function availability
Currently, 'SMCCC_ARCH_FEATURES' SMC call handler unconditionally returns 'SMC_OK' for 'SMCCC_ARCH_SOC_ID' function. This seems to be not correct for the platform which doesn't implement soc-id functionality i.e. functions to retrieve both soc-version and soc-revision. Hence introduced a platform function which will check whether SMCCC feature is available for the platform. Also, updated porting guide for the newly added platform function.
